摘　　要：以油页岩渣为原料,采用NaOH熔融水热合成法和NaOH溶液水热合成法合成了沸石。利用X射线图谱、FT-IR图谱和Cr6+吸附实验探讨了样品的结构及吸附性能。结果表明,NaOH熔融水热合成法合成的为Na-A型和SOD型沸石混合物,NaOH溶液水热合成法合成的为Na-P型和SOD型沸石混合物;2种合成方法对Cr6+的吸附率相差不大,考虑到合成的成本,选用NaOH溶液水热合成法;随着NaOH溶液浓度的增加,产品对Cr6+的吸附率增大,当NaOH溶液浓度为8mol/L时,吸附率可达到89.1%。Zeolites are synthesized by NaOH fusion hydrothermal synthesis and NaOH solution hydrothermal synthesis methods. The samples are characterized by XRD, IR and Cr6＋ adsorption experimentation. The results show that the main crystallinity in zeolitized of oil shale residue by NaOH ＇fusion hydrothermal synthesis method are Na-A and SOD, by NaOH fusion hydrothermal synthesis method are Na-P and SOD. Influence of different synthesis methods on adsorption ratio of Cr6＋ is not notable. From the economic point of view, the optimal method is NaOH solution hydrothermal synthesis method. Cr6＋ adsorption ratio of synthesized products increases with the increase of NaOH concentration, when NaOH concentration is 8mol/L,adsorption ratio reaches 89. 1%.
